number of small holes, I, sufficient to discharge the liquid freely.

The cups may be three or four inches in depth, or more or less, if preferred, and are best arranged by being soldered to a stout wire, J, which passes through the center of the bottom of each, and at such distances from each other that the lip of each cup is about one inch from the bottom of the next, and that the two extreme cups extend to within about an inch of the head of the cylinder.

The ends of the wireou which they are strung fit each into a socket in the head of the cylinder.

I'.he liquid entering at the supplyport fills the space behind the bottom, of the first cup, and passes in a thin sheet between the shell and the outsidepofthecnp, being rapidly cooled in its progress; then passes through the small holes in or near the lip of the cup into the cup and space between it and the next cup, and on in a thin sheet again between the second cup and the shell, through the holes in or near the lip of the second cup, and thus on nntilit reaches the discharge-port.

By this arrangement a comparatively large quantity of liquid is kept constantly cooled to a very low temper-ature.

This-arrangement is shown in Figure 4, showing the supply-port at A, and the cups F F F arranged upon the stout wire J, extending through the entire length of the cylinder.

For the purpose of cooling soda water on draught, the cooler is most advantageously made with a series of cooling-cylinders, connected together by suitable.

tubes, and of the proper length and size to be placed in the icecompartment of the soda apparatus, as shown at- Figure 5. I

What I claim as my invent-ion,'aud desire to secure by Letters Patent, is- I 1. A cooler, having a metallic shell and inner walls of sufiicieut strength to resist the pressure of fermented or artificially aerated liquids, and so arranged by means of the relative size of the shell and the interior walls, and by means of a thread raised on the interior wall or the inside of the shell, or a wire wound substantially as set forth, that the liquid-to be cooled shall be carried spirally in a thin sheet around the interior wall and in contact with the inside of the shell, substantial] y as described.

2. A cooler, having a metallic shell, and within the shell a series of cups arranged substantially as hereinbe-fore set forth, the whole being of sufficient strength to resist the pressure of fermented or artificially aerated liquids.

' 3. As apart of apparatus for drawing fermented or artificially aerated liquids, or liquids in any way charged with carbonic acid gas, a cooler constructed with a cylinder or a series of cylinders, made with either, or any, or all of the arrangements of the interior of the cylinders hereinbefore described.
